Amavuta yo kwisiga menshi ni iki?

Amakuru Yibanze

Amavuta menshi ya entropiya (HEAs) ni amavuta avangwa no kuvanga ibipimo bingana cyangwa ugereranije binini (mubisanzwe) ibintu bitanu cyangwa byinshi. Mbere yo guhuza ibyo bintu, ibisanzwe byuma bigizwe nibice bibiri cyangwa bibiri byingenzi bifite umubare muto wibindi bintu.

Kurugero, ibintu byinyongera birashobora kongerwaho ibyuma kugirango bitezimbere imiterere yabyo, bityo bikarema icyuma gishingiye ku cyuma, ariko mubisanzwe mukigereranyo gito cyane, nkibipimo bya karubone, manganese, nibindi mubyuma bitandukanye. Kubwibyo, all-entropy alloys ni icyiciro cyibikoresho.

Ijambo "all-entropy alloys" ryahimbwe kubera ko kwiyongera kwa entropiya yo kuvanga ari hejuru cyane iyo hari umubare munini wibintu bivanze, kandi ibipimo byabo birasa hafi.

Porogaramu ibyiringiro bya entropiya yo hejuru iragutse cyane, biterwa ahanini nuburyo bwihariye bwihariye bwimiterere nubumara. Hano hari porogaramu mubice byihariye:

1.Icyogajuru: Bitewe n'imbaraga nyinshi, ubukana bwinshi, kwihanganira kwambara cyane hamwe nubushyuhe bwo hejuru, all-entropy alloys ni nziza cyane mugukora moteri ya roketi, ibice bya satelite hamwe nibikoresho byubaka indege bigomba gukora mubushyuhe bwinshi nibindi bikabije ibidukikije. Mubyongeyeho, all-entropy alloys irashobora kandi gukoreshwa mubice byingenzi byimodoka ya hypersonic no mumirima nka blade turbine ya aeroengine.

2.Inganda zikoresha amamodoka: Kurwanya ingaruka hamwe no kwangirika kwangirika kwinshi kwa entropie alloy ituma bakora neza cyane Ideal ya moteri yimodoka, kwanduza, chassis hamwe nibigize umubiri Ishusho. Ibiranga bigira uruhare mukuramba numutekano wimodoka.

3.Inganda za elegitoroniki: Bitewe nibiranga amashanyarazi menshi, amashanyarazi menshi hamwe nubushobozi bwo gukingira amashanyarazi menshi, entropie alloys ifite uburyo bwinshi bwo gukoresha mugukora ibikoresho bya elegitoronike, imiyoboro ihuriweho hamwe nizuba. Ibi bizafasha gutwara imikorere kunoza imikorere na miniaturizasi yibikoresho bya elegitoroniki.

4.Ingufu za kirimbuzi nibindi bikorwa bya gisirikare: Usibye ibyasobanuwe haruguru, amavuta menshi ya entropie arashobora kandi gukoreshwa mugukingira ikirwa gito cya kirimbuzi, gutwikira hejuru yibikoresho byicyuma nibindi bikorwa bya gisirikare cyangwa ingufu za kirimbuzi. Ibi birerekana uburyo bwagutse bwa entropiya yo hejuru murwego rutandukanye rwibidukikije nibisabwa.

5.Ubukanishi bwubaka no guhindura ingufu no kubika: Amavuta menshi ya entropiya ateganijwe kugira uruhare runini mubijyanye nubukanishi bwububiko bitewe nuburyo bwiza bwubukanishi. Mugihe kimwe, agaciro kayo gakoreshwa muguhindura ingufu no kubika nabyo bikwiye kwitabwaho nubushakashatsi

Iperereza.

6.Ibikoresho byubuvuzi: Biocompatibilité hamwe na ruswa irwanya amavuta menshi ya entropiya ibaha ibisabwa mubijyanye nubuvuzi, nko gutera amenyo, ibikoresho byamagufwa, nibindi bikoresho byubuvuzi bisaba kwimikwa igihe kirekire mumubiri wumuntu. Muri rusange, hamwe niterambere rihoraho hamwe niterambere ryubumenyi nikoranabuhanga hamwe no gukenera ibikoresho bishya, hashobora kuvugwa ko ibisubizo byinshi byubushakashatsi niterambere byerekeranye no gukoresha amavuta menshi ya entropiya azavuka mugihe kizaza.
